Mr. Potter spent more than 20 years as a public relations executive for two large health insurers--CIGNA and Humana--but left the industry after witnessing practices he felt harmed American health care consumers.

He has decided to come forward in the hopes of stopping the health insurance industry from once again derailing meaningful reform.
